    Question

    There are 151 accidents during high school sports lessons. 54 of these accidents were caused by cheerleading. Suppose you want to take a random sample of 5 out of the 151 without backtracking. What is then the probability that not a single accident is caused by cheerleading?


    1. FALSE: (49/151)5
    2. FALSE: 1-(54/151)5
    3. FALSE: (49/151)(48/150)(47/149)(46/148)(45/147)
    4. FALSE: (49/151)(48/151)(47/151)(46/151)(45/151)
    5. TRUE: (97/151)(96/150)(95/149)(94/148)(93/147)

    1. (49/151)5: Incorrect
    2. 1-(54/151)5: Incorrect
    3. (49/151)(48/150)(47/149)(46/148)(45/147): Incorrect
